ORA-32618: incorrect use of MODEL PREVIOUS function

The previous() can only be used within the iterate … until clause of a model statement.

Because this function is used outside of the iterate clause, the following statement throws the ORA-32618: incorrect use of MODEL PREVIOUS function error:

select *
from
   dual 
model
   dimension by (0 as id )
   measures     (0 as num)
 rules
   (
      num[iteration_number] = previous(num[iteration_number])
   );
